Looking for some opinions on spokes/lacing for these rims. I was going to use butted spokes like Sapim Lasers or DT Revos but heard that those weren't recommended for disc wheels. Also thinking of going 2x - some of the other carbon rim manufacturers recommend 2x. Looks like most folks are going 3x with a variety of different spokes - butted, straight and bladed. Any thoughts?

They are fine for disc wheels.

ENVE recommends 2x due to their nipple hole layup alignment. Not a consideration or issue with the Nancy rims. You can't go wrong with 3x and it provides a better tangential spoke angle for transmitting torque (braking & drive forces), but 2x works fine too.
This is a case where the opinions FAR outweigh any actual benifits or detriments from choosing one spoke or cross pattern over another.

(Cheap) Chinese Carbon Rims?

I have ABSOLUTELY no interest in the wider rims, or the "benefits" of the wider rims. I give absolutely ZERO ****s about the wider rims. So Please, spare the "lectures" on the nature of wider rims and tires and resistance. I am exceedingly well-versed in the nature of those topics.

I am simply interested in whether or not anyone has anything notable to say about the reliability of the NARROW rims being run tubeless, preferably with Stan's tape or gorilla tape.

Whatever wide lovers...theyre alive!! This is my narrow rimmed lb wheel. I used gorilla tape and at first I tried a maxxis ikon it didn't inflate. Luckily I can return it due to them sending me the Wrong model. I then got a specialized fast trak, which is tubeless ready, and it inflated easily.So it's all about which tire you use. I now regret I used gorilla tape as I think Stan's tape would work fine and it's light. Glad I didn't get the wide ones like aIl the other sheep, I Mean real Mountain bikers. these are so light and they re gonna fly.

I hope this is okay. I have a set of the Bonty rim strips and valves that I was going to use but my builder taped them without asking me so I have no use for them anymore. Let me know if you are looking for a set of the Rhythm Pro 29er strips and we can try to work something out.

does anyone know why carbon rim manufacturers don't use extremely impact resistant composites in the outer layer? For example Kevlar or spectra. They aren't much more expensive than most reg. Carbon fiber. I've used Kevlar in the carbon fiber frames I make for myself, and the only downside is that it fuzzes during sanding. It looks really cool and would almost eliminate all of the rim wall cracks

Maybe it is just not as marketable. If it is harder to use in production that wouldn't help either. Yeah, it is a bugger to cut, and some have told me more susceptible to breaking down in sunlight but that I don't know. Most people want stiff/light so there may be limits on how much stuff they can use in a rim.

Forgive me if I've missed this but can someone explain the 'New Process' I keep seeing references too? What was changed, issues addressed, benefits?

Thx

I don't know if the "new process" rims will be an improvement over the "old process rims but if you have a preference you need to specify when you place your order according to Brian at LB. They are shipping out both new/old randomly right now. Mine just shipped yesterday and I will be receiving "old process" rims.

I'm not sure that an impact resistant layer would do any good for the kind of damage a carbon rim gets. The rim sees more crushing forces, like hitting a curb at speed, not damage like being hit by a flying rock. I can see that would be a good thing to add to the underside of a frame downtube or something, but I think it would just add weight to a rim.

I emailed LB about this and they didn't really answer my question as to the difference between the two processes. Sounds like they are still waiting to see how the new process rims are received by customers and how they hold up. Anyone got the new process rims and have any thoughts?

(answer from Nancy)

"Yes, we sell both the process for 29er wide rims currently, and most part are still with the past process. Because the testing for new process haven't been finished, and we like to know how the customers ride on new process rims. Then make a decision when to change all molds for new process. And for customers' riding test, it will take around a few months.
It is easy to see which rims are with new process, the serial number is "R02XXXXXXX". And for rims with the past process, it is with " R29C xxxxx"."

So.... Customer beta testing. Greeeeaaat. I guess that's why the are cheap. I dunno, I would volunteer for that.
